摘要：Dynamically tuning the emission of circularly polarized luminescence (CPL) materials through external stimuli is fascinating because of their fundamental and application interests. In this work, light-responsive and luminescence-tunable CPL-active materials are synthesized by mixing achiral helical polymer containing vibration-induced emission (VIE) molecules and spiropyran (SP) with a chiral helical polymer. Through regulating the distinct emission of VIE molecules and the reversible photoisomerization of SP, the dynamic Forster resonance energy transfer (FRET) can be explored to reversibly control the emission color of CPL in different states after light-controlled isomerization. This project is the first comprehensive investigation of CPL-active materials with VIE properties. Finally, taking the advantage of the multistimuli responsive CPL signal in different states, an "INHIBIT" logic gate with CPL signal output based on the combination of control of UV/vis light irradiation time and state alternation is constructed.
